This leaderboard only displays AUPRC scores and may not reflect final rankings based on overall challenge evaluation criteria. See the "Problem Description" page for full evaluation criteria.
Average Precision (AP), also equivalent to area under the precision–recall curve (AUPRC or PRAUC) with no interpolation, ranges from 0 to 1. For more information, see sklearn's documentation. The goal is to maximize AP. In the case of multilabel classification, this metric will be calculated as a macro-average, with the final metric being an unweighted mean of AP values calculated for each label separately.

PETs Prize Challenge: Advancing Privacy-Preserving Federated Learning Official Rules
This document outlines the official rules for the PETs Prize Challenge: Advancing Privacy-Preserving Federated Learning (Challenge), co-sponsored by the Information Technology Laboratory (ITL) of the National Institute of Standards and Technology (NIST) and the National Science Foundation (NSF) (Organizers). Nothing within this document or in any supporting documents shall be construed as obligating the Department of Commerce, NIST, NSF, or any other Federal agency or instrumentality to any expenditure of appropriated funds, or any obligation or expenditure of funds in excess of or in advance of available appropriations.
This Challenge is being conducted in parallel with a similar prize challenge sponsored by the government of the United Kingdom. Participants in this Challenge, whether they are individuals, entities, or team members, are prohibited from participating in the UK prize challenge, and participants in the UK prize challenge are likewise prohibited from participating in this Challenge. Individuals, entities, or team members who are found to have entered both the US and the UK challenges will be disqualified from participating in either. Additional details regarding eligibility are included at Sections 1.9 Minimum Submission Requirements and 9.2 Eligibility Requirements.
This Challenge seeks innovators to help mature federated learning approaches and build trust in adoption by accelerating the development of efficient privacy-preserving federated learning (PPFL) solutions. The U.S. and UK collaboration to develop parallel prize challenges was announced during President Joe Biden’s Summit for Democracy as part of a grand challenge series focused on advancing democracy-affirming technologies.
The PETs Prize Challenge is a multi-track, multi-phase competition with the total amount of prize awards valued at up to $800,000. The Organizers are seeking solutions that leverage a combination of input and output privacy techniques to drive innovation in the technical development and application of privacy enhancing technologies (PETs).
This Challenge will consist of four phases, and members of the public who are eligible to compete (see additional details regarding eligibility herein), whether as an individual, a team, or a private entity (Participants), may participate as either Blue Team Participants or Red Team Participants in accordance with the timelines and instructions set forth herein. The Blue Team Participants and Red Team Participants will compete in different phases of the Challenge.
In Phases 1 and 2, Blue Team Participants will generate and build solutions to the problems presented by this Challenge. In Phase 3, the Red Team Participants will compete against one another while they test the top Blue Team Participants’ submissions, as chosen by the Judges Panel. The results of the tests performed by the Red Teams will be used to determine the winners of Phase 2 among the Blue Team Participants. In Phase 4, the top-performing Blue Team Participants will be invited to participate by contributing their Phase 2 solutions to an open-source website.
The Challenge will begin with an abstract and a concept paper in Phase 1, followed by a solution development contest in Phase 2, which will involve the development and implementation of PPFL solutions. For Phase 3 a red teaming contest will test the privacy protections of the top implemented solutions from Phases 1 and 2. There are no fees needed to enter any stage of the Challenge. Blue Team Participants must participate in Phase 1 in order to compete in Phase 2. Red Teams will be distinct from the Blue Teams that they are testing, and no overlap or cross-over between membership on Blue Teams and Red Teams will be permitted.
Artificial intelligence (AI) and other emerging analytics techniques are amplifying the power of data, making it easier to discover new patterns and insights, ranging from better models to predict the impacts of climate change to new methods for detecting financial crimes. However, while data is enabling innovation and insights across sectors, it can still be challenging to harness the full potential due to the imperative for adequate privacy protections and without proper privacy preserving mechanisms, use of such data may result in more harm to individuals and society.
This Challenge seeks to engage Participants in developing effective PPFL solutions to enable the use of valuable sensitive data without moving the data or compromising the privacy of individuals whose information is contained within the data set.
Federated learning, or more generally collaborative learning, shows huge promise for machine learning applications derived from sensitive data by enabling training on distributed data sets without sharing the data among the participating parties. This results in a machine learning model that aggregates local models obtained from distributed parties. As data from each participating party does not need to be shared, the approach already provides a general level of privacy. However, as the global federated model is trained, the parameters related to the local models could be used to learn about the sensitive information contained in the training data of each client. Similarly, the released global model could also be used to infer sensitive information about the training datasets used.
1.3 Participation Options for Blue Team Participants:
Blue Team Participants will develop solutions that enhance privacy protections across the lifecycle of federated learning. This Challenge offers two different data use cases – financial crime prevention, or Track A, and pandemic response and forecasting, or Track B. Blue Team Participants may develop solutions directed to either one or both tracks. If Blue Team Participants choose to develop and submit a more generalizable solution to run on both Track A and B, they can also qualify for additional prizes dedicated to Generalizable Solutions. See Section 2 for additional details.
Track A: Financial Crime Prevention. The United Nations estimates that up to $2 trillion of cross-border money laundering takes place each year, financing organized crime and undermining economic prosperity. Financial institutions such as banks and credit agencies, along with organizations that process transactions between institutions, such as the SWIFT global financial messaging provider, must protect personal and financial data, while also trying to report and deter illicit financial activities. Federated learning shows huge promise for machine learning applications derived from sensitive data by enabling training on distributed data sets without sharing the data among the participating parties. Using synthetic datasets provided by SWIFT, Participants will design and later develop innovative privacy-preserving federated learning solutions that facilitate cross-institution and cross-border anomaly detection and combat financial crime. Participants in Track A will have the opportunity to engage with subject matter experts and banking regulators as they develop their solutions.
Track B: Pandemic Response and Forecasting. The COVID-19 pandemic has taken an immense toll on human lives and has had an unprecedented level of socio-economic impact on individuals and societies around the globe. As we continue to deal with COVID-19, it has become apparent that better ways to harness the power of data through analytics are critical for preparing for and responding to public health crises. Federated learning approaches could allow for responsible use of sensitive data to develop cross-organization and cross-border data analysis that would result in more robust forecasting and pandemic response capabilities. Using synthetic population datasets, Participants will design and later develop PPFL solutions that can predict an individual’s risk for infection. If an individual knows that they are likely to be infected in the next week, they can take more prophylactic measures (masking, changing plans, etc.) than they usually might. Furthermore, this knowledge could help public health officials better predict interventions and staffing needs for specific regions.
Generalizable Solutions. Cross-organization, cross-border use cases are certainly not limited to the financial or public health domains. Developing out-of-the-box generalized models that can be adjusted for use with specific data or problem sets has great potential to advance the adoption and widespread use of PPFL for public and private sector organizations in multiple sectors. Participants will develop a solution using both the Track A and Track B datasets to be eligible for additional awards dedicated to generalizable solutions.
1.4 Goals and Objectives:
Organizers seek to mature federated learning approaches and build trust in adoption by accelerating the development of efficient PPFL solutions that leverage a combination of input and output privacy techniques to:
- Drive innovation in the technological development and application of novel privacy enhancing technologies;
- Deliver strong privacy guarantees against a set of common threats and privacy attacks; and
- Generate effective models to accomplish a set of predictive or analytical tasks that support the use cases.
1.5 Summary of Phases:
The Challenge will occur across four phases. The Blue Team Participants will compete against one another in Phases 1 and 2, and the Red Team Participants will compete against each other in Phase 3. The results of the Red Team Participants’ competition in Phase 3 will be used to assist in evaluating the Blue Team Participants’ submissions in Phase 2, and the top Blue Team solutions from Phase 2 will be invited to participate in Phase 4 by making their winning solutions open and available to the public.
Phase 1: Concept Paper. Blue Team Participants will produce a technical white paper (“Concept Paper” or “White Paper”) setting out their proposed solution approach. Technical papers will be evaluated by a panel of judges across a set of weighted criteria. Participants will be eligible to win prizes awarded to the top technical papers, ranked by points awarded.
Phase 2: Solution Development. Blue Team Participants will develop working prototypes of their solutions. These solutions are expected to be functional, and capable of being used to train a model against the evaluation data set, with measurement of relevant performance and accuracy metrics. Solutions will be evaluated by a panel of judges across a set of weighted criteria. This evaluation will determine a pool of up to 9 finalist Blue Team Participants that may advance to testing by Red Teams. The ideal pool to advance will include the 3 top-scoring solutions from each of Track A, Track B, and generalizable solutions. If a top generalizable solution is also a top 3 performer in a data track, then the next highest scoring solutions for that track will also be selected to advance to the red teaming phase. If a top generalizable solution results in an overlap of a top 3 performer across data tracks, the judges may also select the next highest scoring solution to advance to the red teaming phase. The intent is to advance as many solutions, up to 9, as possible for red teaming, however, advancement will be at the sole discretion of the judges.
Phase 3: Red Teaming. Red Team Participants will develop and implement attack scenarios to test the concepts and solutions developed by Blue Team Participants in Phases 1 and 2. Up to 9 final Blue Team Participants’ solutions from Phase 2 judges' evaluations will advance to this red teaming, where the privacy guarantees will be tested against a set of common privacy attacks. Results of the Red Team attacks will be used to determine the final rankings among the Blue Team Participants for Phase 2. The three best performing Red Team Participants will be awarded prizes for Phase 3.
Phase 4: Open Source. Up to 5 of the top-scoring Blue Team Participants’ may be invited to participate in this Phase by contributing their solutions to an open source repository or website, as set forth in Section 1.7, below.

1.9 Minimum Submission Requirements
The Organizers are interested in efficient and usable federated learning solutions that provide end-to-end privacy and security protections to harness the potential of AI for overcoming significant global challenges while preserving privacy and security. The four-phase Challenge will be administered by DrivenData (https://www.drivendata.org/) on behalf of the Organizers.
To be eligible for prizes in the Challenge, Participants must:
Meet all eligibility requirements laid out herein.
Visit (https://www.drivendata.org/) to register for a DrivenData account then navigate to the Challenge Website (https://petsprizechallenge.drivendata.org) to sign up for either Phase 1 as a Blue Team Participant, or for Phase 3 as a Red Team Participant before the Phases’ respective registration deadlines. If you already have a DrivenData account, you can sign up directly as a Blue Team or Red Team Participant during the appropriate Phase registration period on the Challenge website (https://petsprizechallenge.drivendata.org).
Not participate using more than one DrivenData account. A Participant, whether an individual, a team, or a private entity, using more than one account is deemed cheating and, if discovered, will result in disqualification from the Challenge and any other affected challenges and may result in banning or deactivation of affected DrivenData accounts. DrivenData reserves the right to request information from Participants for the purpose of any investigation of suspected cheating. Failure by a Participant to respond to these requests (including failure to furnish the requested information) within 10 days is grounds for disqualification from the Challenge. Participants are prohibited from privately sharing source or executable code developed in connection with or based upon data received from the Challenge outside of their Team, and any such sharing is a breach of these Challenge Rules and may result in disqualification.
Electronically acknowledge acceptance of these Official Rules and satisfy all of the requirements described herein.
If participating as a Red Team participant, electronically acknowledge and sign the Non-Disclosure Agreement for the Challenge.
For Phase 1, submit via and according to the instructions on the Challenge website (https://petsprizechallenge.drivendata.org) an abstract and a Concept Paper that meet the criteria outlined in the Rules for Phase 1 on or in advance of the submission deadlines. Blue Team Participants’ abstracts must briefly describe a proposed track specific or a generalized federated learning (FL) solution and PETs that could be employed within that solution. Blue Team Participants’ Concept Papers must incorporate and expand on the abstract further detailing the technical approach, privacy guarantees, anticipated privacy issues, and privacy tradeoffs, as well as the anticipated performance of the model.

2. Rules for Phase 1 - Concept Paper
The Organizers are interested in efficient and usable federated learning solutions that provide end-to-end privacy and security protections to harness the potential of AI for overcoming significant global challenges without sacrificing privacy and security.
Phase 1 of the Challenge is intended to source detailed concepts for innovative and practical solutions. In this stage, Participants are asked to propose federated learning solutions which incorporate privacy-preserving techniques. Participants are free to determine the set of privacy technologies used in their solutions, with the exception of hardware enclaves (or similar approaches) and other specialized hardware-based solutions.
Phase 1 invites all eligible, registered Blue Team Participants to submit an abstract and concept paper detailing input and output privacy technique integration into a federated learning (FL), or more generally, a collaborative learning model.
Participants will have the opportunity to expand their knowledge in real world federated learning use cases by hearing from and possibly engaging directly with financial crime and public health data subject matter experts and active practitioners in these fields. In addition to the opportunity to win monetary prizes, eligible Blue Team Participant winners may also be invited to present their solutions at the next Presidential Summit for Democracy currently slated for Spring 2023.
Blue Team Participants will follow the instructions set forth in the Minimum Submission Requirements section above to sign up for a DrivenData account and register for Phase 1. Participants may form teams using the DrivenData upon creation of an account and registration.
Upon registration, the Organizers intend to provide all participants with the following for Tracks A and B, as available:
- Detailed concept briefs which further detail the technical use cases for each Track
- Sample Data and data schema relevant to each Track; and
- A centralized machine learning data model for each Track.
The Organizers also intend to schedule webinars or other similar engagements with use case track subject matter experts to enhance Blue Team Participants understanding of data sharing needs, applicable compliance needs, and threats to each specific use case. Further information regarding these events will be posted to the Challenge website or on the Challenge website’s forum. (https://petsprizechallenge.drivendata.org)
Blue Team Participants may write and submit their abstract and Concept Paper at any time up until the Challenge’s posted deadlines for each requirement.
There are two data use case tracks in the contest—Track A: Financial Crime Prevention and Track B: Pandemic Response and Forecasting. Blue Team Participants can elect to apply their solution to either or both tracks and are required to specify which. There are four possible cases:
- Your solution is for Track A
- Your solution is for Track B
- The solution is a generalized solution for both Track A and Track B. A generalized solution is one that can be executed and evaluated on both data use case tracks where there is the same core privacy architecture and where adaptations to specific use cases are relatively minor and separable from a shared codebase.
- There are two separate solutions: one for Track A and one for Track B. In such a case, you are required to make two sets of submissions that meet the submission requirements—one for each solution. This is required for both solutions, when further developed, to be eligible in the following Solution Development Phase. However, each team can win at most one prize in the Concept Paper Contest whether they have one or two sets of submissions.
As you propose your technical solutions, be prepared to clearly describe the technical approaches and sketch out proof of or justification for privacy guarantees. Participants should consider a broad range of privacy threats during the model training and model use phases and consider technical and process aspects including but not limited to cryptographic and non-cryptographic methods, and protection needed within the deployment environment.
There are additional privacy threats that may be specific to the technical approaches proposed by the participating teams. Teams will be asked to clearly articulate any other novel privacy attacks that are addressed through their solutions.
Successful technical approaches and proofs of privacy guarantees will include the design of any algorithms, protocols, etc. utilized, as well as formal or informal arguments of how the solution will provide privacy guarantees. Participants will clearly list any additional privacy issues specific to the technological approaches used and justify initial enhancements or novelties compared to the current state-of-the-art. Participant submissions must describe how the solution will cater to the types of data provided to participants and how generalizable the solution is to multiple domains. Expected efficiency/scalability of improvements, privacy vs. utility trade off should be articulated, if possible, at this conceptual stage.
The use and purpose of licensed software or proprietary hardware should also be anticipated and acknowledged as the conceptual stage evolves.
If so desired, Blue Team Participants may initiate solution development based upon the information and sample data received in Phase 1 and concurrently with the writing of the Phase 1 Concept Papers in Phase 1. Blue Team Participants who chose to do so, but fail to meet the minimum submission requirements or criteria in Phase 1, will be ineligible to advance to Phase 2 and must immediately delete all Phase 1 data.
To be eligible for prizes, a successful submission for Phase 1 will include two separate elements: a one-page abstract and a Concept Paper.
Abstract: The one-page abstract must include a title and a brief description of the proposed solution, including the proposed privacy mechanisms and architecture of the federated model. The description should also describe the proposed machine learning model and expected results with regard to accuracy. Successful abstracts will outline how solutions will achieve privacy while minimizing loss to accuracy, a proposed solution, and the anticipated results, as more fully described on the Challenge Website. Abstracts must be submitted by following the instructions on the Challenge Website. Abstracts will be screened by the DrivenData and Organizers’ staff for contest eligibility and used to ensure the composition of the judging panel’s expertise aligns to proposed solutions that will be evaluated throughout the course of the Challenge. Feedback will not be provided.
Concept Paper: The Concept Paper should conceptualize solutions that describe the technical approaches and lay out the proof of privacy guarantees that solve a set of predictive or analytic tasks that support the use cases. Successful Concept Papers will incorporate the originally submitted abstract and be no more than ten pages in length. References will not count towards page length. Participant submissions shall:
- Include a title and abstract for the solution
- Clearly articulate the selected track(s) the solution addresses, understanding of the problem, and opportunities for privacy technology within the current state-of-the-art.
- Clearly describe the technical approaches and proof of privacy guarantees based on their described threat model, including:
- The design of any algorithms, protocols, etc. utilized,
- The formal or informal arguments of how the solution will provide privacy guarantees.
- Clearly list any additional privacy issues specific to the technological approaches used.
- Justify initial enhancement or novelty compared to the state-of-the-art.
- The expected efficiency and scalability of the privacy solution,
- The expected accuracy and performance of the model,
- The expected tradeoffs between privacy and accuracy/utility,
- How the explainability of model outputs may be impacted by your privacy solution,
- The feasibility of implementing the solution within the competition timeframe.
- Describe how the solution will cater to the types of data provided to participants and articulate what additional work may be needed to generalize the solution to other types of data.
- Articulate the anticipated use and purpose of licensed software.
- Be free from typographical and grammatical errors.
Participants should refer to Section 7 on general submission requirements for additional guidance and style guidelines.
Judges will score the Concept Papers against the weighted criteria outlined in the table below. Solutions will need to carefully consider trade-offs between criteria such as privacy, accuracy, and efficiency, and should take the weightings of the criteria into account when considering these trade-offs. Concept Papers must also demonstrate how acceptable levels of both privacy and accuracy will be achieved – one must not be completely traded off for the other (a fully privacy-preserving but totally inaccurate model is not of use to anyone). Proposals that do not sufficiently demonstrate how both privacy and accuracy will be achieved will not be eligible to score points in the remaining criteria.
Evaluation Criteria and Judging
Submissions to Phase 1 will undergo initial filtering to ensure they meet minimum criteria before they are reviewed and evaluated by not fewer than three members of the expert judging panel. These minimum criteria include:
- Participant meets eligibility requirements;
- All required points listed above are included; and
- Proposed solutions are coherently presented and plausible.
Submissions that have passed the initial filtering step will be reviewed for technical merit by members of the expert judging panel and evaluated against the following evaluation criteria.
|Topic||Specific Criteria||Weighting (/100)|
|Technical Understanding||Does the white paper demonstrate an understanding of the technical challenges that need to be overcome to deliver the solution?||10|
|Privacy||Has the white paper considered an appropriate range of potential privacy attacks, and how the solution will mitigate those?||25|
|Accuracy||Is it credible that the proposed solution could deliver a useful level of model accuracy?||10|
|Efficiency and scalability||Is it credible that the proposed solution can be run within a reasonable amount of computational resources (CPU, memory, communication, storage), when compared to a centralized approach for the same machine learning technique?
Does the white paper propose an approach to scalability that is sufficiently convincing from a technical standpoint to justify further consideration, and reasonably likely to perform to an adequate standard when implemented?
Solution scalability will be evaluated primarily for a) the number of connected banks / financial institutions involved, b) volume of transactions, and c) volume of customer data held by banks
|Adaptability||Is the proposed solution potentially adaptable to different use cases and/or different machine learning techniques?||5|
|Feasibility||Is it likely that the solution can be meaningfully prototyped within the timeframe of the challenge?||10|
|Innovation||Does the white paper propose a solution with the potential to improve on the state of the art in privacy enhancing technology?
Does the white paper demonstrate an understanding of any existing solutions or approaches and how their solution improves on or differs from those?
|Usability and Explainability||Does the proposed solution show that it can be easily deployed and used in the real world and provide a means to preserve any explainability of model outputs?||5|
Participant solutions may be grouped by similar technical approaches for ease of comparison. Reviewers’ scores will be aggregated for each submission. The specific scores will not be released publicly (unless required by law) or provided to the submitting participants. The submissions will be ranked based on their score and receive prize awards of 1st Prize, 2nd Prize, or 3rd Prize. Submissions that have the same scores will be presented to the entire panel for review and merit-based ranking. All Blue Team Participants whose concept papers meet the minimum criteria described above will win invitations to advance to Phase 2.
NOTE: As detailed herein, Phase 3 of the Challenge includes the disclosure of Blue Team Participants’ Phase 1 and 2 submissions, including Concept Papers, to Red Team Participants, and by submitting an entry to any phase of the Challenge, Blue Team Participants agree to such disclosure. Accordingly, Blue Team Participants may wish to take appropriate measures to protect any intellectual property contained within their Challenge submissions, and such protection should be sought prior to entering them into the Challenge.
3. Rules for Phase 2 - Solution Development
The objective of the Challenge is to develop a PPFL solution that is capable of training a machine learning model on the datasets, while providing a demonstrable level of privacy against potential threats.
This PPFL solution should aim to:
- Provide robust privacy protection for the collaborating parties;
- Minimize loss of accuracy in the model; and
- Minimize additional computational resources (including CPU, memory, communication), as compared to a non-federated (centrally trained) approach, and a baseline federated learning approach.
In addition to this, the evaluation process will reward Participants who:
- Show a high degree of novel innovation;
- Demonstrate how their solution (or parts of it) could be applied or generalized to other use cases;
- Effectively prove or demonstrate the privacy guarantees offered by their solution, in a form that is comprehensible to data owners or regulators; and
- Consider how their solution, or a future version of it, could be applied in a production environment.
Phase 2 is open to Blue Team Participants who won invitations because their Concept Papers met the minimum criteria described in the Phase 1 Scoring Process. No further registration will be required for the invitees to advance to Phase 2; however, invited Blue Team Participants should make necessary updates to their registration via their DrivenData account to reflect any changes in team composition or contact information.
The Solution Development Phase will have two data use case tracks matching those previously from the Concept Paper Phase—Track A: Financial Crime Prevention and Track B: Pandemic Response and Forecasting. Teams can elect to participate in either or both tracks, with solutions that apply to one track individually or with a generalized solution. Each solution must correspond to a concept paper that met the requirements from the Concept Paper Phase.
Each data use case track has a prize category for top solutions. All solutions that apply to Track A or Track B are eligible for a prize within that respective track. Teams who submit solutions for Track A and Track B are eligible to win a prize from each track.
Additionally, participants can enter a third Generalized Solutions category of prizes for the best solutions that are shown to be generalized and applied to both use cases with minor adaptations. Teams submitting generalized solutions are eligible for Generalized Solution prizes in addition to being eligible for prizes from both Track A and Track B.
Upon challenge launch, the Organizers intend to provide Blue Team Participant access to:
- Detailed concept briefs and instructions for each Track; and
- Robust development dataset(s) relevant to each Track that either comprises 3 nodes or may be partitioned into 3 or more nodes.
A range of support will be provided to Participants during the Challenge including opportunities to engage with data protection and public and private sector organizations operating in arenas relevant to the Challenge’s tracks, as well as ad-hoc technical support from the third-party data providers.
Participants are—subject to having detailed their solution in their concept paper proposal—free to determine the set of privacy technologies used in their solutions within the parameters of the challenge, with the exception of hardware enclaves and other specialized hardware-based solutions. For example, any de-identification techniques, differential privacy, cryptographic techniques, or any combination thereof may be used.
Participants will prepare and submit code for a centralized baseline model (MC) and a privacy-preserving federated model (MPF) along with documentation for how to train and make inferences from the models, including a list of dependencies (e.g., a requirements.txt), and their own experimental privacy, accuracy, and efficiency metrics for the two models via the DrivenData Challenge Website.
In order to be eligible for prizes, Participants must submit all source code used in their solution for review. If the solution includes licensed software (e.g., open-source software), Participants must include the full license agreements with the submission. Include licenses in a folder labeled “Licenses”. Within the same folder, include a text file labeled “README” that explains the purpose of each licensed software package as it is used in your solution. DrivenData/NIST are not required to contact Participants for additional instructions if the code does not run. If DrivenData is unable to run the solution, including any requirement to download a license, the submission may be rejected. Blue Team Participants shall contact DrivenData immediately with any concerns about this requirement.
Evaluation Criteria and Judging
Submitted solutions will be deployed and evaluated on a technical infrastructure hosted by DrivenData. This infrastructure will provide a common environment for the testing, evaluation, and benchmarking of the solutions.
NOTE: As set forth in these Rules, the Organizers reserve to themselves the right, in their sole discretion, to revise the terms governing any phases taking place after the effective date of any such revision. The Organizers anticipate that the diversity and complexity of solutions proposed in Phase 1 may influence the final design of Phase 2. The Organizers will utilize abstracts and monitor and assess Participant feedback and discussions on the Challenge Website forum and during the informational webinars with financial crime and pandemic forecasting use cases subject matter experts, the level of diversity of solutions, judges’ preliminary review of the Concept Papers and technical capabilities and resources available for evaluation in order to refine requirements. Any refinements will be made in consultation with the data subject matter experts, the judges panel, DrivenData, and the UK Challenge partners. Announcements regarding updated requirements, processes, and judging and evaluation criteria will be posted on the Competition Website’s forum not less than 10 days prior to the Phase launch and posted publicly to the Competition Website at the start of the Red Team Participant registration. Participants should follow discussions and updates on the website forum (https://petsprizechallenge.drivendata.org/) to stay current on all Challenge news and events. Initial evaluation of the developed solutions will be based on a combination of quantitative metrics, and qualitative assessments by judges according to the following criteria:
|Privacy||Information leakage possible from the PPFL model during training and inference, for a fixed level of model accuracy.
Ability to clearly evidence privacy guarantees offered by solution in a form accessible to a regulator and/or data owner audience
|Accuracy||Absolute accuracy of the PPFL model developed (e.g., F1 score).
Comparative accuracy of PPFL model compared with a centralized model, for a fixed amount of information leakage
|Efficiency and scalability||Time to train PPFL model and comparison with the centralized model.
Network overhead of model training.
Memory (and other temporary storage) overhead of model training.
Ability to demonstrate scalability of the overall approach taken for additional nodes
|Adaptability||Range of different use cases that the solution could potentially be applied to, beyond the scope of the current challenge||5|
|Usability and Explainability||Level of effort to translate the solution into one that could be successfully deployed in a real world environment.
Extent and ease of which privacy parameters can be tuned.
Ability to demonstrate that the solution implementation preserves any explainability of model outputs.
|Innovation||Demonstrated advancement in the state-of-the-art of privacy technology, informed by above-described accuracy, privacy and efficiency factors||10|
Phase 2 may include one round of interaction with the teams so that they can provide any clarification sought by the judges. Comparison bins may be created to compare similar solutions. Solutions should make a case for improvements against existing state-of-the-art solutions.
Track-specific prize finalists will be determined based on the factors above for solutions submitted to each data track. Generalizable solutions run on both Tracks will be evaluated by combining the factors above, along with dedicated judging of the generalizability of the solution as described on the Challenge Website. as follows:
|Performance on Track A||See table above||40|
|Performance on Track B||See table above||40|
|Generalizability||Assessment of the technical innovation contributing to generalizability of the solution to the two use cases, and potential for other use cases||20|
As with Phase 1, the outcomes of trade-off considerations among criteria as made in the Concept Papers should be reflected in the developed solution. Solutions must meet a minimum threshold of privacy and accuracy, as assessed by judges and measured quantitatively, to be eligible to score points in the remaining criteria.
The top solutions ranked by points awarded for Track A, Track B, and Generalized Solutions will advance to Red Team evaluation as described below. The results of the Red Team evaluation will be used to finalize the scores above in order to determine final rankings.
Rules for Phase 3 - Red Teaming
The objective of Phase 3 is to test the strength of the privacy-preserving techniques of the developed PPFL modes through a series of privacy audits and attacks. Red Team Participants will plan and launch audits and attacks against the highest-scoring solutions developed during Phase 2.
Red Team Participants will register through the DrivenData Challenge Website. Red Teams must be distinct from the Blue Teams they are testing. (https://petsprizechallenge.drivendata.org/) Red Team registration will remain open from November 10, 2022 to December 2, 2022.
After close of registration period, Red Team Participants will receive access to:
- A selection of Concept Papers submitted during Phase 1; and
- Evaluation environment specifications, development data, and documentation to allow Red Team Participants to prepare for attacks.
Red Team Participants may begin constructing their attack scenarios upon access to Concept Papers and the red-teaming materials. Red Team Participants shall develop attack scenarios based upon the range of solutions identified in the Concept Papers. The Red Team scenario development period will run concurrently with Blue Team solution development. The Organizers intend to provide informational sessions or webinars with subject matter data and practicing experts in the use case fields.
Following the testing and judges review of developed solutions, Red Team Participants will enter the Red Team Attack period. As many as 9 of the top ranked solutions by points awarded may advance. Ideally, this would include 3 of the top ranked solutions in each track and at least 3 generalizable solutions. The intent is to advance the most possible solutions while limiting overlap across the tracks and with the generalized solutions. Therefore, if a top generalized solution is also one of the top 3 in one of the data tracks, then the next best-scoring solution in that data track will also be included as a finalist in the red team evaluation. Likewise, if a generalized solution scores in the top three of both data tracks, the next highest ranking solution from both data tracks may be advanced at the judges’ discretion. However, if the judges determine that less than 9 solutions meet the minimum criteria for privacy and accuracy, then fewer than 9 solutions will be advanced to the red teaming phase.
The Organizers may assign any Red Team Participants any set of Blue Team finalists' solutions. The number of Blue Team solutions assigned to each Red Team will not exceed five. Red Team Participants may be assigned Blue Team solutions where different solutions use different techniques and/or be for different tracks (Financial Crime Prevention, Pandemic Forecasting, or Generalized). Therefore, Red Team Participants should be prepared to attack any and all Blue Team solutions regardless of those solutions' underlying privacy mechanisms or track designations.
Assigned Blue Team solutions will be made available to the assigned Red Team Participants at the start of the Attack Period in order to initiate their privacy attacks. Datasets for common baseline privacy attacks may also be provided to Red Teams. Using their attack scenarios Red Teams will attempt to exploit vulnerabilities in each of the Blue Team solutions’ privacy-preserving techniques. Red Team Participants will document exposed vulnerabilities found in a single cumulative attack report per solution and submit the reports no later than the end of the Red Team Attack period.
Red Team Participants must submit required evaluation materials, including attack reports, by the submission deadline providing evidence addressing the evaluation criteria below. Reports will include justification if the attacks were not successful (supporting the robustness of the solutions). Red Team Participants must evaluate all assigned solutions to be eligible for prizes.
See the DrivenData Challenge Website at the start of the contest for more information on submission criteria for the attack report. A complete submission (corresponding to one assigned blue team solution) should consist of the following items:
- A technical report of no more than 4 pages, describing the the privacy claims tested by the attack(s), the attack(s) themselves, and experimental results showing their effectiveness
- An appendix of no more than 8 pages, to provide additional details and proofs (note that reviewers will not be required to read the appendix)
- The implementation used to generate the experimental results in the report
- A code guide of no more than 1 page, describing how the code implements the attack(s) described in the report
A template or example of the attack report will also be provided for reference. (https://petsprizechallenge.drivendata.org/)
Red Team Contest Evaluation Criteria and Judging
Success of red team attacks will be assessed by a panel of judges using the factors below, in order to evaluate the empirical results reported, the approaches taken and the severity of the flaws the Red Teams are able to exploit. Red team results on the same solutions will be compared to provide individual scores. Each Red Team’s attacks across the solutions it was assigned to attack will be assessed for consistency, difficulty, novelty, rigor, and practicality to inform scores per the criteria below.
NOTE: As set forth in these Rules, the Organizers reserve to themselves the right, in their sole discretion, to revise the terms governing any phases taking place after the effective date of any such revision. The Organizers anticipate that the diversity and complexity of solutions proposed in Phase 1 will influence the final design of Phase 3. The Organizers will utilize Concept Papers, monitor and assess Participant feedback and discussions on the Challenge Website forum and during the informational webinars with financial crime and pandemic forecasting use cases subject matter experts, along with the level of diversity of solutions, and technical capabilities and resources available for evaluation in order to refine requirements. Any refinements will be made in consultation with the data subject matter experts, the judges panel, DrivenData, and the UK Challenge partners. Announcements regarding updated requirements, processes, and judging and evaluation criteria will be posted on the Competition Website’s forum not less than 10 days prior to the Phase launch and posted publicly to the Competition Website at the start of the Red Team Participant registration. Participants should follow discussions and updates on the website forum (https://petsprizechallenge.drivendata.org/) to stay current on all Challenge news and events.
|Effectiveness||How completely does the attack break or test the privacy claims made by the target solution? (e.g. what portion of user data is revealed, and how accurately is it reconstructed)?||40|
|Applicability / Threat Model||How realistic is the attack? How hard would it be to apply in a practical deployment?||30|
|Generality||Is the attack specific to the target solution, or does it generalize to other solutions?||20|
|Innovation||How significantly does the attack improve on the state-of-the-art?||10|
